Answer 4

\(\frac{1}{3}(5n+12)+\frac{1}{3}n=-1\)
You have to get the \(n\) on its own. Start by getting rid of the fractions by multiplying.
Is the second term supposed to be \(\frac{1}{3n}\) or \(\frac{1}{3}n\)?

Answer 5

There is a left side of the equal sign, and a right side.

The left side is (1/3)(5n+12) + (1/3)n

The right side is -1

Anything you do to one side you must do to the other to maintain equality.
